Among them, some stories about algebra, some history about geometry, a set of equations in ancient China and some research about ancient triangles in China can help students understand the emergence and development of mathematics knowledge, grasp the inseparable relationship between mathematics and production and life, and stimulate students' patriotic enthusiasm by understanding the great achievements of teachers' country in mathematics. "Clever use of materials" and "golden section" play an important role in extending and digesting textbook knowledge, and are important materials for training students' thinking and cultivating mathematics consciousness.
